scan: score scanned at 600dpifilter: score filtered with 2-point algorithm explained in High Quality ScanningI provide the original scanned version and the filtered, because the filter does some changes (smoothening, sharpening borders) and some portions of the scan get lost sometimes (when they are too small e.g.) - so you can choose your favorite. You may ask me for a manually cleaned version.
